Status of EPNG NAS Simplification Enhanced EBB Project The enhanced EBB Project will be broken down into four phases: – Phase 1 : Implemented early June 2009 This will include: the new color scheme and logos, tree menu, Standards of conduct, SOC/COC notice subscription, operational flow data, contract authorization forms, and FERC filings.
